5w30 will work, although, unless you're going to be in really fridgid temperatures, I would have gone with 10w30.

HOWEVER, that said, you would probably be better off with a diesel oil like Mobil Delvac or Rotella T in the 15w40 rating. Those oils are still forumulated for engines with flat tappet valvetrains, and all the newer oils are formulated for roller cams. The newest formulations, which you can buy very reasonably even at WalMart, are formulated to stand up to continuous oil temperatures approaching 250 degrees, which is the temperature in the newest diesel engines with EGR and particulate filters.

Now let the arguing begin!

And just in passing, anything newer than about 1982 should have a 195 degree thermostat in it for the engine to run properly. If you don't have a catalytic converter, it's probably not crucial.

Ya I used to always run thicker oil thinking it was better but after running the he'll outta my 97 F-150 for 405,000 km's using mobile one synthetic 5w30, I seen that thicker oil isn't always better. And it's cold here in the mornings , I'm in the rocky mountains. But I like that info on the oil being formulated for roller cams... That may be a problem in this old454... Would still like to find a 5 w 30 synthetic from mobile 1 for my engine.

I have no real stake in this conversation...just readin' for entertainment and a bit of general knowledge. Great Thread!

rollnsmoke, In your search for 5W30 Mobil1; I may have something of interest to you. My daily driver is a Benz S600 twin turbo. The required oil(to avoid warranty hassle) is Mobil1 0W30 E spec. It used to be pretty hard to find but even good ole' Wally World stocks it now in my neck of the woods. That v12 is one seriously high strung lump and it has run without a sneeze now for 140K miles and I don't baby it. In actuallity, I really get a kick out of terrifying unsuspecting passengers. It's just entertaining to watch a little old lady's face wrap back around her ears......Sorry Grandma

It pours like orange juice but seems to provide the needed protection at least as well as a heavier oil. Granted, there are no flat tappets involved. Either way, it may be worth a look.

Ya I have a 2010 jeep rubicon and it calls for 5w20 engine oil...I now have 0w20 synthetic mobile one and they say it has better protection that the regular 5w20...plus its supposed to save fuel. poors like water...guess we'll see how it works out...

Ok..well i was thinking of selling the pace Arrow but now im having second thoughts...it's just so fun to drive....

Took it on my four day shift last week in the mountains where i work...I NEED A WOOD STOVE!!!! lol
I really like this thing because it is more like a house inside than a camper..
Can anyone tell me where I can read about the history of my 1983 Pace Arrow? I read some literature on how the Fleetwood bounder was made but didn't c anything on the P.A??
There was supposed to be a luxery model and i'm wondering if mine is that one?? It has the couch/bed and two nice chairs with a table in the middle.
Just needs the woodstove to complete the package...the heater in this thing would never keep u warm during the winter months...but the plumbing is all in the same area so as long as the heater is going the water won't freeze. The black and grey water tanks will freeze however and I have a few ideas on how to prevent that from happening...
I put the one size larger tires on and i'm sure it will make a huge difference in the snow because these are all terrain tires....
